Twenty-plus text utilities, zero setup

Most text chores don't deserve a script: flip a name upside down for a bio, count words before publishing, normalise case across a list, extract values from delimited logs, or spell out a number in words for a cheque-style document. Pick a utility from the rail, paste your text, and the transformation happens instantly — locally, with nothing uploaded.

Frequently asked questions

What string operations are included?

Case conversion, reversing, repeating, word and character counting, frequency analysis, line sorting, deduplication, whitespace and punctuation removal, accent stripping, delimited extraction, hex/binary conversion, number-to-words and more — over twenty utilities in one place.

How do I generate a strong password?

Pick Password Generator in the rail. It creates high-entropy passwords locally; pair it with the NTLM hash tool when working with Windows identity systems.

Can I clean up copy-pasted text from PDFs or emails?

Yes — the whitespace removers (extra spaces, empty lines, line breaks) plus accent stripping fix the usual artifacts of copied text in a couple of clicks.

How does word frequency help with writing?

Paste an article to see which words dominate. Writers use it to catch repetition; SEOs use it to sanity-check keyword distribution before publishing.
